SPECIFICATION forming part of Letters Patent No. 299,219, dated May 27,1884. Application filed October 1,1883. (No model.)

.To all whom t may concern:

Be it known that I, JAMES It. HAIGHT, of Adrian, in the county ofLenawee and State of Michigan, have invented new and useful Improvementsin Fountain-Pens, and I do hereby declare that the following is afull,clear, and exactdescription thereof, reference being had to theaccompanying drawings, which forni a part of this specification.

This invention relates to certain new and useful improvements in theconstruction and operation of that class of pens known as fountain-pens.

The invention consists in the peculiar construction of the various partsand their combinations, by means of which a more perfect and regularfeed is obtained than is had in the pens of a similar class now in use,and wherein the danger of accidental overflow of the ink is reduced tothe minimum, as more fully hereinafter described.

Figure l is a central longitudinal section o f my improved pen. Fig. 2is a sectional elevation. Fig. 3 is a cross-section on the line :1: a:in Fig. 1.

In the accompanying drawings, which form a part of this specification, Arepresents a cylinder-fountain, one end of which is rigidly closed, asat a, while into the opposite end is screwed a hollow plug, B, one 'endof which projects beyond the end of the fountain, as shown in Fig. 1,the bore of the projecting end being larger than the bore of theinclosed end.

Eis another plug or pin, the diameter of which is the saine as thesmaller bore of the plug B, into which the plug E slips, or is screwed,if preferred, the space left between this plug and the wall of thelarger bore of the plug B forming a space in which to insert the pen,which may be of any of the known constructions. This plug E is split orslotted, as shown at b, for apart of its length, and a small hole ororifice, c, connects said slot with the fountain-chamber.

D is a cap, which is slipped into the space between the two plugs on theoppositeside from the pen C, and is made of the form substantially asshown in the drawings, to inclose the space between it and the pen,thereby forming a chamber into which the slot in the plug E opens, suchchamber being for the purpose of holding a sponge or other suitableabsorbent. A slot, d, is cut in each .side of this cap coincident withthe lower end of the slot in the plug E, to admit air at that pointbetween the absorbent and the fountain.

F is a detachable leap, designed, when the penis in use, to engage withthe projecting end of the plug B to protect the pen, and when the latteris in use to engage with the opposite end of the fountain-cylinder, asshown, to form, an extension of the pen-holder.

It will be noticed in this construction that when the pen is in usethere is free access of air to the ink in the slot in the plug E, bymeans of which the column of ink is retarded in its :dow or held inabeyance by atmospheric pressure, the orifice in the plug E, connectingwith the fountain, allowing the air to pass and the ink to flow out inthe sponge, which latter feeds ink to the pen as fast asrrequired, suchsponge being saturated from the fountain for that purpose through themeans described. Vhen the pen is' held upright in position afterwriting, the ink above the sponge makes a supercharge, causing lsome topass out into the pen, where the capillary attraction ofthe concave ofsuch pen holds the ink ready for use.

It will also be noticed that the fountain is detachable from thesponge-holder, and that the latter may be made adjustable tc differentlengths of pens, which, when in place, are securely held by the springof the plug E, obtained by its being split, as described.

I am aware of Patent No. 260,134, and make no claim to the constructionshown therein.

What I claim as my invention isl. The combination of the cylinder-reservoir closed at the top, the porous material or sponge in the chamberformed by the pen, and a shoe or cap, a central plug with an orice andslot affording communication between said reservoir and such porousmaterial, saidV slot also opening to the air through coincident openingsin the cap or shoe, substantially as and for the purposes set forth.

2. The cylindrical ink-reservoir, open at its lower end only, incombination .with a dei tachable holder inclosing a central plug,slotted and bored to afford communication between such fountain and thepen, the shoe or cap and pen, by means of which a chamber is IOO fornedto receive the porous material, the parts being constructed andoperating substantially as described and shown.

nish the requisite atmospheric pressure at a point betweensuch porousmaterial and the fountain, substantially as set forth.
